exact description of the invention, such as will.

enable others skilled in the art to which it ap pertains to make and use the same.

My invention consists of a spinning-frame comprising certain novel constructions. and combinations of parts, as will be hereinafter V described and specifically claimed, whereby a convertible mechanism for moving the ringrails of the machine is provided, which by certain changes, can be adapted for making alternately weft yarn or warp yarn.

The object of my invention .is to do away with the use of two spinning-frames, one for spinning weft and the other for spinning warp, and. to adapt a single spinning-frame for both purposes alternately, and thus save a great deal of room as well as avoid expense to the manufacturer of Weft and warp yarns.

In the accompanying drawings, Figure 1 is afront view of a portion of a spinning-frame as improved by meand as used for makingweft, parts of the supporting-hangers being broken away in order to better expose to view the working parts in the rear thereof. Fig. 2 is a horizontal section of the same in theline a: a: of Fig. 1. Fig. 3 is a similar section showing the mechanism as used for making warp. Fig. 4 is a vertical section in the line yy of Fig. 2. Fig. 5 is an elevation of a cam used with the mechanism for making weft. Fig. 6 is a diagram of aweft-bobbin and its yarn load wound by the aid of said cam. Fig. 7 is an elevation of a cam used with the mechanism for l'llflk'.

ing warp, and Fig. 8 is a diagram of a warpbobbin and its load wound by the aid of said can]. Fig. 9 is a detail view, partly in plan and section, of one of the band-clamps used on the vertica1ly-oscillating ring-rail rods.

- A in the drawings represents an ordinary spinning-frame; B, ring-rail; O, mechanism used in making weft, and D mechanism used 1n making warp.

The frame A isofordinary construction,and is provided with spindles a, rings b, ring-rails B, and other ordinary machinery for operating the movable parts.

In Figs. 1 and 2 the machinery shown is adapted for spinning weft and the mechanism employed for the purpose of vertically reciprocating the ring-rails and also winding the bobbins in proper shape, as will be seen. The said mechanism receives motion by means of a toothed wheel, 6, of a cam-shaft E, from the usual change gears provided on spinningframes. The camshaft, which is suitably hung to the frame A, is provided with a cam, c, which operates aroller, f, 011 a sliding rod, F. The sliding rod F is provided with a guide-slot, f, by means of which it slides on the camshaft E, and a forked head, f", which is pivoted by means of a pin, f, toa leverarm, G. The front end, 9, of the lever-arm G is supported in a guideslot, h, of a suitable hanger, H, of the frame A, while the rear or fulcrum end, g,is pivoted at g to a suitable hanger, H, of the frame, which hanger is provided with a longitudinal slot, h, in which the pivot y can be adjusted. The lever-arm G is provided with a screw, I, suitably hung between bearings of the lever-arm, and to said screwa nut, i, is secured, which is fitted partly around the said lever-arm, and is thus caused to move in a straight line when the screw I is turned. The front portion of the screw I is provided with a ratchet-wheel, i, which is, by the motion of arm G, moved against a pawl, i, adjustably pivoted by means of a threaded pin, i having a nut, and a slot, h in the hanger H. The front end of the screw I is providedlwith a crankhandle, '6 for the purpose of turning the screwby hand, as will be seen. To the top of the nut z a band-clamp, i, is pivoted by means of a pivot, 13 and this clamp} is provided with a slot, 43 and a clamp-screw, i. The end of a steel band, i is inserted into the slot i and clamped tightly therein by the screw 5. Near its center the arm G is provided with a guide-pulley, 9*, around Whichthe steel band i passes toward a movable cross-brace, J, to which it is suitably fastened at 3'. This cross-brace J consists of a Hat beam, j, having [(0 a slot, j", and branching portions terminating with end flanges, j, which latter are, by means of bolts j, fastened to two horizontal longitudinal fiat bars, K. These bars K are supported upon flanged guide-pulleys k, suitably sup ported by hangers 7t, or otherwise, and at their lower sides they are provided with clampscrews 78, holding steel bands k to the bars, which steel bands run over the pulleys It, and thence down to clamp-heads b, provided on the lower ends of vertically-oscillating railrods 1) of the ring-rails B. The clamp-heads b are fastened by means of set-screws b to the rods 11, and they are provided with slots 1), (see Fig. 9,) into which the ends of the steel bands 7a are inserted, and to which they are fastened by means of set-screws 7c. The weight of the ring-rails is in a great measure counterbalanced by pivoted weighted crank-levers L, suitably attached to the frame and bearing against rounded projections Z of lugs l, suit ably secured to the ends of the bars K. The bars K are prevented from leaving the pulleys is opposite the weighted levers I: by pins fastened to the hangers 7;, and being barely in contact with the upper surfaces of the said bars. The bars K are provided with screwthreaded holes it for the purpose of receiving the bolts j, there being two sets of such holes, one set occupied by the said bolts, as shown in Fig. 2, and the other set by the bolts, as shown in Fig. 3, thus permitting the brace J to be fastened to the bars K in two different positions, as circumstances require.

The position ofthe brace J (shown in Fig. 3) is the one it occupies when the spinning-frame is adapted for making warp-yarns, and while in this position the band i is not necessary, the slotj" being brought directly in line with a screw, M, and is occupied by a roller, m, pivoted at m. to a nut, m"', which takes the place of the nut i on the left-handed screw M which has been substituted for the right-handed screw 1, (shown in Figs. 1 and 2,) attached to the lever-arm G. In connection with this adjustment of the parts of the spinning-frame the ratchet-wheel 13 of the screw I is properly attached to the left-handed screw M, so as to be operated by the pawl i, the crank-handle i" being fastened to the front end of the screw M. Said screw, by said handle, may be operatedhby hand, for the purpose hereinbefore set fort The sliding rod F (shown in Figs. 1 and 2) is replaced by a similar but longer sliding rod, F, which performs the same functions-i. 0., that of causing the lever-arm G to oscillate in accordance with the peripheral formation of the revolving cam on shaft E. The roller f is operated by a cam, N, substituted for the cam e on the shaft E. The rollerf is held against the cam I by the superior weight of the ringrails over the counterbalancing-weight of the levers L, and thus the ring-rails are moved up and down at the rate of the speed of the revolving cam, which is on the shaft E.

\Vhen the machine is arranged, as shown in Figs. 1 and 2, for the purpose of making weft, the cam 6 causes the levcrarm G to oscillate and move the ring-rails up and down in such manner that the yarn load (0 shown in Fig. (i) is built up by conical layers 0 of the weft. as required for weaving purposes, each pair of the layers 0 being formed during a revolutionof the cam e,and after each revolution of said cam the ratchet-wheel i being turned by the pawl i a certain distance, and the nut 6 thereby moved a slight distance forward, and the crossbrace J brought nearer to the lever-arm G, it will be apparent that the ring-rails are slightly raised after the formation of each pair oflayers 0,and thus provision is made for the correct formation of the succeeding layers 0, and this goes on until the bobbins are of the required size, when the machine is stopped, the bobbins removed, fresh bobbins o' provided in the usual manner, and the screw I, by means of the crank-handled, turned backward until the not i is moved to its place of starting, whereupon the machineis set to work again.

Vhen the machine is arranged for making warp, as shown in Fig. 3, the cam N on the shaft E causes the lever-arm G to oscillate and move the cross-brace J forward and backward, thereby raising and lowering the ringrails. This causes the formation of a yarn load, P, as shown in Fig. 8, composed of cylindrical layers 12 of yarn. At every revolution of the cam N the ratchet-wheel i is moved by the pawl i thereby causing the nut m to move a slight distance toward the fulcrum g" of the lever-arm G,and thereby decreasing the stroke of the roller m, crossbrace, J, and ring-rails B. In consequence of this decrease of strokes the yarn loads are shaped with conical end portions, 1), as seen in Fig. 8. Vhen the yarnloads P have attained their proper size, the machine is stopped, the filled bobbins p are removed, fresh bobbins 17* provided, and by means of the crank i" the screw M is turned backward until the nut at has arrived at its starting-point, whereupon the machine is set in motion again to repeat its operation.
